RS-232 mode: Fig. 4 Serial network in RS-232 This mode can only be used in case of communication between 2 individual devices (point-to-point connection). The maximum distance in RS-232 is 15 m at 19200 baud. RS-485 mode: Fig. 5 Serial network RS-485 mode This mode is used more often as it allows connection of several slaves on the bus. It also has other advantages such as immunity to EMC disturbances and a greater inter-device distance than in RS-232. The maximum distance in RS-485 is 1200 m. 2.3.2 Termination resistance If the communication mode used is RS-485, there must be a termination resistance of 120Ω at both ends of the network. A termination resistance can be added directly in VPGate if it is positioned at the end of a segment. It is connected using 2 DIP switches (when delivered, VPGate is preset without a termination resistance). Note 1: Note 2: To ensure proper operation of the termination, the 2 switches must be in the same position. In RS-232 mode, these 2 DIP switches must be on TERM OFF.

2.4 Selection of the PROFIBUS address Use the switches 1,2,4,8,16,32,64 to select the PROFIBUS address of the VPGate. (VPGate default factory setting is address 3). The label next to each switch corresponds to its weight. PROFIBUS address must be set to a value between 0 and 126. Ex: To set address 3, set the switches 1 and 2 to ON.

3. Software Setup for PROFIBUS DPV0 3.1 Configuration tool for PROFIBUS DP Master DPV0 The setup of VPGate PROFIBUS to serial is done using the configuration tool of the PROFIBUS network. The configuration is automatically sent to the PROFIBUS slaves (VPGate PROFIBUS) during the network initialisation phase. The detailed configurations hereafter was created as examples using the PROFIBUS configuration tools from third party vendors, "Console" of Woodhead and "HW Config" of SIEMENS. However the principle is the same with other PROFIBUS master configuration tools of the market place. 3.2 Include VPGate into a project Before to continue, it is mandatory to create a project into the third party configuration tool. The project must include a PROFIBUS network and a master port. 3.2.1 Import the VPGate GSD file into the third party configuration tool. This GSD file allows you to use the VPGate as a PROFIBUS slave device. It is named PROC6980.GSD and it is located on our website under PROCENTEC https://procentec.com/service-support/gsd-files. It is necessary to import this GSD file into the third party configuration PROFIBUS to have the VPGate device appearing in the list of slave devices to be included on the network. HW config. TIA portal Console, Woodhead VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 13/82

3.2.2 Insert VPGate into the network configuration The different stages are as follows: From the list of PROFIBUS devices, insert VPGate on the network. Setup the appropriate PROFIBUS address of the VPGate (this value must match with the one configured on the VPGate hardware (DIP switches) HW config. TIA portal Console, Woodhead Note: The communication baudrate of VPGate is automatically defined according to the configuration of the PROFIBUS DP master. 3.3 VPGate parameters 3.3.1 General parameters Once VPGate is inserted into the PROFIBUS network configuration, it is necessary to configure the serial line. HW config. TIA portal Console, Woodhead VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 14/82

Name Description Possible values MODBUS RTU Protocol selection Mode selection MODBUS ASCII transparant Extended diagnosis Enable or disable PROFIBUS extended diagnosis Enabled Disabled Interframe silence Specifies a time that must be respected between received and transmitted frames in ms. 20 65535 ms (*) In MODBUS RTU, data are coded on 8 bits. In MODBUS ASCII, data are coded on 7 bits. In those modes, parameter "data bits" is ignored. (**) In MODBUS ASCII, if there is not parity bit ("No parity"), others MODBUS equipments on the network must be configured with 2 stop bits. 3.3.2 Setup VPGate in TRANSPARENT mode In this mode, data exchange is full duplex on the serial link, without any master / slave relation. Frames detected over the serial link are immediately transferred to the PROFIBUS inputs, starting at the offset 0. Also, if a serial frame format is detected in the PROFIBUS outputs, it is immediately transferred to the serial link. In order to do so, it is necessary to define how frames are delimited. To setup VPGate in transparent mode: Set the parameter "Protocol selection" on "TRANSPARENT": HW config. TIA portal Console, Woodhead VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 16/82

Then setup parameters dedicated to transparent mode: HW config. TIA portal Console, Woodhead Name Description Possible values NULL (0x00) SPACE (0x20) LF (0x0A) CR (0x0D) EOF delimiter (1) Defines how an end of frame will be detected CR LF LF CR User defined Length in 1st byte On timeout (2) Fill-in unused bytes (3) Defines if unused bytes in PROFIBUS inputs frame must be modified in end of frame character Enabled Disabled Add frames counter (4) Defines if a frame counter is added at the beginning of PROFIBUS inputs and outputs frames Enabled Disabled Add and control CRC 16 Defines if a CRC16 must be checked in the data received from the serial equipment, and must be added to the data sent to the serial equipment. Enabled Disabled VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 17/82

(1): If this parameter is set on User defined, the end of frame character taken into account is the one specified by parameter "User defined EOF". If it is set as on timeout, the reception timeout taken is the one defined in the serial link configuration. (2): When "EOF delimiter" is set to on timeout, only detection of frames received from serial line is on timeout. On PROFIBUS side, 1st byte must be used to specify the length of received/sent frame (cf. 3.4.1). (3): When "EOF delimiter" is set on length in 1st byte or on timeout, the filled value is 0x00. (4): This counter is used as a trigger: If this parameter is enabled, 1st byte of PROFIBUS outputs must be a counter incremented each time data are available and must be sent. Relevant data begin at 2nd byte. Otherwise, the frame is copied from the 1st byte as soon as a change on PROFIBUS outputs is detected. If this parameter is enabled, 1st byte of PROFIBUS inputs is incremented each time a new frame was received on serial link. Useful data are copied following this counter. Otherwise, received frame is copied from the 1st byte. Note: Each principle in TRANSPARENT mode is detailed in 3.4.1. The inter frame silence parameter leads to the following behaviour: If there is no recently detected frame, VPGate sends frames through the serial line without waiting for an inter frame time. But, when there is a detected frame through the RX line, VPGate will wait for the inter frame time before sending the following frame through TX. 3.3.3 Setup VPGate as MODBUS Master To use VPGATE as MODBUS master, proceed as follows: Adjust first of all parameter "Protocol selection" on "MODBUS RTU" or "MODBUS ASCII" depending on the protocol used. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 18/82

Select then the parameter "VPGate Master/Slave" on "Master". HW Config, TIA portal Console, Woodhead Then setup general parameters dedicated to MODBUS master mode: "CRC/LRC" and "Retries" HW Config, TIA portal Console, Woodhead Name Description Possible values CRC / LRC Defines if CRC (MODBUS RTU) or LRC (MODBUS ASCII) must be controlled Enabled Disabled 0 Retries Number of iterations before signalling a timeout 1 2 3 Set the parameter inter frame silence to specify the minimum time VPGate can take to send a new MODBUS request to a slave after receiving the last reply (see the figure below). VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 19/82

Then setup the different scenarios in order to define the different MODBUS commands to be sent as well as how VPGate is going to send them: HW Config, TIA portal Console, Woodhead VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 20/82

The parameters of a scenario are as follows: Name Description Possible values NOP (0x00) Disabled Read coils (0x01) Read coils (0x02) Read registers (0x03) MODBUS Function MODBUS command to be sent (NOP means that the current scenario and the following are disabled) Read registers (0x04) Write coil (0x05) Write register (0x06) Read status (0x07) Write coils (0x0F) Write registers (0x10) Passe-trame (0x7F) Slave address Address of MODBUS slave receiving the command. 1 to 247 included Frame trigger The command can be sent: Cyclically (timer) On change of value of PROFIBUS output registers Once at power up of the VPGate Each cycle On change Only once Cycle time Period of timer to send the command (only if Frame trigger = Each cycle) 100 ms 500 ms 1 s VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 21/82

Name Description Possible values 5 s 10 s Cycle time Period of timer to send the command (only if Frame trigger = Each cycle) 30 s 60 s Polling (= no delay) Address of 1st bit or register Address of 1 st MODBUS bit or register 0 to 65535 included Qty of bits or registers (*) Number of MODBUS bits or registers to be exchanged 0 to 1952 included (*) : For one scenario, it is possible to set a maximum of 122 registers with functions 3, 4 and 10 or a maximum of 1952 bits with functions 1, 2, 15. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 22/82

It is possible to configure up to 20 scenarios. For example: SCENARIO 1 Function Read (0x03) From Modbus slave address 1 Every 1s SCENARIO 2 Function Write (0x10) To Modbus slave address 3 Up on change of value HW Config, TIA portal Console, Woodhead 3.3.4 Generic master mode: PASS-FRAME function This mode allows data exchange in transparent mode between PROFIBUS and the serial link. However, VPGate must behave as a master, so it always has to send a request first. Then, the slave can reply. This data exchange mode is possible when VPGate is configured as a MODBUS master. For each scenario, it is possible to choose function 0x7F (pass frame). This function is not a MODBUS function. It is specific to VPGate. It allows VPGate to send on serial link a frame made of some bytes received from the PROFIBUS outputs. If a reply is required, it is possible to specify the number of bytes expected. Received bytes are then copied into PROFIBUS inputs. Example: the following scenario is configured: MODBUS Function = 0x7F Slave Address = x (not taken into account) Frame Trigger = Each cycle Cycle Time = 500ms Address of 1st bit or reg = 0x0008 (number of bytes to send on serial line) Qty of bits or registers = 0x0007 (number of bytes to receive on serial line) VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 23/82

If no reply is detected before the configured timeout, or if more bytes or less bytes are received, a diagnostic is triggered. If no reply is required, the parameter "Address of 1st bit or reg" must be set to 0. 3.3.5 Setup VPGate as MODBUS slave To use VPGATE as MODBUS slave, please proceed as follows: Select the parameter "VPGate Master/Slave" on "Slave" (by default VPGate is configured as a slave). The MODBUS slave address of VPGate is in the field named "Address in slave mode" HW Config, TIA portal Console, Woodhead Adjust parameter "CRC/LRC" (CRC control enabled in RTU mode or LRC control enabled in ASCII mode: Set the parameter inter frame silence to specify the time VPGate will take to respond to a MODBUS master request (see the figure below) VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 24/82

When configured as a MODBUS slave, VPGate supports the MODBUS functions 1, 2, 3, 4, 5, 6, 7, 15, 16 and 23. An exception message is sent when using a function which is not above listed. It is possible to read or write a maximum of 122 registers at once for functions 3, 4, 10 and 23, or a maximum of 1952 bits at once for functions 1, 2 and 15. If there is no PROFIBUS communication, an exception frame is sent in reply to any MODBUS query. 3.4 Insertion of Input / output modules The last stage is the choice of input / output modules to be acceded by the PROFIBUS master. It is possible to insert "INPUT WORDS" modules to size PROFIBUS inputs, and "OUTPUT WORDS" modules to size PROFIBUS outputs (1 WORD = 2 bytes). 3.4.1 When VPGate is in TRANSPARENT mode In transparent mode, modules to be inserted depend on the maximum number of bytes that can be received or transmitted. As an example, if a maximum of 150 bytes can be exchanged over serial link, in reception and transmission, a minimum of 75 "OUTPUT WORDS" and 75 "INPUT WORDS" must be inserted. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 25/82

Insertion of modules: Console, Woodhead HW Config, TIA portal It is possible to exchange up to 244 PROFIBUS input bytes and up to 244 PROFIBUS output bytes. In following examples, 244 input bytes and 244 output bytes are inserted. Principle: When end of frame is detected with a specific character: In this example, end of frame character is the ASCII code "CR" (0x0D). After reception of the first byte from serial link: If no byte was received after the configured timeout, an error is signalled and no data is sent over PROFIBUS inputs. If the frame length is superior to the number of PROFIBUS input bytes, and the received frame is valid, an error is signalled the frame is sent truncated over PROFIBUS inputs. If a change was detected in PROFIBUS outputs If an end of frame character is detected into the frame, data are sent over serial link from the 1st byte to the end of frame character included. Following bytes are ignored. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 26/82

When the frame length is known: The 1st byte must contain the quantity of following bytes. After reception of the first byte from serial link: If expected bytes are not received after the configured timeout, an error is triggered and no data is sent over PROFIBUS inputs. If the frame length is superior to the number of PROFIBUS input bytes, and the received frame is valid, an error is triggered and the frame is sent truncated over PROFIBUS inputs. If a change was detected in PROFIBUS outputs If the 1st byte indicates a length superior to the number of PROFIBUS outputs, an error is signalled the frame is sent truncated over PROFIBUS. When the end of frame is detected on timeout: 1st byte of PROFIBUS inputs indicates the number of received bytes. 1st byte of PROFIBUS outputs must indicates the number of bytes to send. After reception of the first byte from serial link: If no more byte is received after the configured timeout, number of received bytes is set in 1st byte of PROFIBUS inputs and received data is sent over PROFIBUS after this length byte. If the length of received frame plus one byte indicating the length is superior to the number of PROFIBUS input bytes, an error is triggered and the frame is sent truncated over PROFIBUS inputs. If a change was detected in PROFIBUS outputs If the 1st byte indicates a length superior to the number of PROFIBUS outputs, an error is signalled the frame is sent truncated over PROFIBUS. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 27/82

Trigger function of the frame counter: The frame counter, when enabled, is added at the beginning of PROFIBUS input and output frames. This counter is incremented each time a new frame is available. It is used to signal that a new frame was received, or to detect a new frame to be sent. In this example, the frame length is known. The byte coding the length into PROFIBUS outputs and inputs is located at the 2 nd byte, afterward the counter. 3.4.2 When VPGate is in Master MODBUS mode. In case of Master MODBUS mode, the input / output module to be inserted directly depend on the definition of the scenarios. As example: Warning: 1 PROFIBUS module doesn t necessarily correspond to 1 scenario. It is actually possible to cover several scenarios with only 1 single module (ex: 1 module "32 INPUT WORDS" to cover 2 scenarios of reading 16 registers from 2 different MODBUS Slaves). VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 28/82

Insertion of the modules: Console, Woodhead HW Config, TIA portal How this Works? It is possible to insert up to 122 read registers and 122 write registers. 3.4.3 When VPGate is in MODBUS Slave mode In MODBUS Slave mode, the PROFIBUS module to be inserted depends on the number of inputs and outputs to be exchanged. As example: Warning: In MODBUS Slave mode, a "OUTPUT WORD" is read by the MODBUS Master and a "INPUT WORD" is written by the MODBUS Master. The size of PROFIBUS input is 64 bytes. The size of PROFIBUS outputs is 16 bytes. Then VPGate gets 32 write registers, accessible for the MODBUS address 0 to address 31, and 8 read registers from the MODBUS address 0 to address 7. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 29/82

It is possible to insert up to 122 read registers and 122 write registers. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 30/82

4. Fail safe mode VPGate PROFIBUS supports the PROFIBUS Fail-Safe mode. When the PROFIBUS master asks the gateway to switch to Fail-Safe mode, the behaviour is as follows: In MODBUS master mode: PROFIBUS outputs are no more received so MODBUS write scenarios are no more processed, until the master goes back to a normal working mode. MODBUS read scenarios are still processed and PROFIBUS inputs are refreshed. In MODBUS slave mode: PROFIBUS outputs are no more received so a MODBUS exception frame in sent in reply to any MODBUS read request of outputs, until the master go back to a normal working mode. A normal reply is sent to any MODBUS write request and PROFIBUS inputs are refreshed. In TRANSPARENT mode: PROFIBUS outputs are no more received so no frame is sent on serial link, until the master go back to a normal working mode. However any frame correctly received from serial link is copied in PROFIBUS inputs. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 31/82

5. DPV1 PROFIBUS acyclic functionalities 5.1 Configuration tools of the PROFIBUS DPV1 master VPGate PROFIBUS to serial provides acyclic access for advanced features: Identification information (I&M) about the gateway, useful for asset management on demand send / receive of MODBUS frames on the serial line VPGate supports: 1 MS-C1 communication with a DPV0 master (usually a PLC), 1 MS-C2 communication (usually a configuration or asset management tool). There are no DTM nor EDD files available. With the DPV1 functionality, a PLC can trigger a MODBUS request on demand. This is convenient in the following cases: Need to read or write more than 122 MODBUS registers Need to access more than 20 MODBUS slaves Need to reconfigure a MODBUS device that was replaced Need to configure the access to a new MODBUS device, without putting the PLC in STOP mode. Essential when it is impossible to change the hardware configuration in RUN mode. Identification informations, TIA portal 5.2 Identification Informations The VPGate is compliant with I&M0 (Identification & Maintenance) functionality of PROFIBUS. This functionality allows the user to get identification information about the device, using a software like Step 7 or TIA portal. VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 32/82

These informations are available on slot 0: Manufacturer ID Order ID Serial Number Hardware version Software version Revision counter Profile ID Profile Specific Type I&M Version I&M Supported 5.3 Acyclic communication in «MODBUS master» mode When the VPGate is configured in MODBUS master mode, it is possible to execute acyclic MODBUS scenarios with the DPV1 functionalities. A messaging system using DPV1 slots/indexes can be used for describing a MODBUS frame, sending it on the serial line, and access to the slave reply. Slot # Index # Function 1 0 COMMAND (1 byte) 1 1 STATUS (1 byte) 1 2 ADDRESS (1 byte) 1 3 FUNCTION (1 byte) 1 4 OFFSET (2 bytes) 1 5 LENGTH (1 byte) 1 6 DATA (1 à 240 bytes) VPGate PROFIBUS to serial manual 30 juni 2017 PROCENTEC 33/82

5.3.1 Description of the index 0 «COMMAND» The index 0 «COMMAND» can be used for start a MODBUS request. Command Bit 7 6 5 4 3 2 1 0 Definition Send = 1 No action = 0 - - - - - - - Bit 7: This bit is used to start the command. The PROFIBUS master must set this bit to 1 when all the indexes are filled-in. This bit resets automatically after the end of the command. The acyclic requests are transmitted between two MODBUS cyclic scenarios. Note: Only one acyclic command is allowed at the time.

7. Diagnostic 7.1 PROFIBUS extended diagnostic In addition to the 6 bytes of standard diagnostic, VPGate manages 27 bytes for extended diagnostic. This allows the gateway to inform the PROFIBUS master about problems in the communication with the serial line equipment. To activate the PROFIBUS extended diagnostic (activated by default), it is necessary to select the parameter named "Extended diagnosis" on "Enabled". HW Config, TIA portal Console, Woodhead The extended diagnostic is sent after the PROFIBUS standard diagnostic. It is structured as follows: Bytes 8-14: 56 bits for general errors Parameter errors Configuration errors Reception error on serial line Time out on serial line Bytes 15-34: 1 byte per scenario to inform about the error. Bytes 1 6 Bytes 7 Bytes 8 14 Bytes 15-34 Standard diagnostic Length of extended diag. General errors Error scenario1 Error scenario20 x x x x 0x 08 0x 34 0x1C 56 bits x x x x The explanation of each error is given in the appendix A.

Appendix B: Format of MODBUS messages The MODBUS functions 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x0F, 0x10, 0x17 are supported by VPGate. The format of each function is detailed using an example for MODBUS RTU and ASCII. The bytes for CRC error check (MODBUS RTU) or LRC (MODBUS ASCII) are mandatory. However, they are not treated if the parameter "CRC/LRC" is disabled (set to "No CRC/LRC").. In MODBUS RTU, data are 8 bit coded. In MODBUS ASCII, data are 7 bit coded. Remind : It is important to differentiate the address of the MODBUS register and the MODBUS register # (number). Actually, the register 1 is at MODBUS physical address 0x0000. In a MODBUS message, it is the address of the register sent. When setting up a scenario, it is also the MODBUS register address that must be configured. Function 1 (0x01) This function allows to read multiple booleans (coils or Discrete outputs). The broadcast mode is not supported.

Exception Message An exception message is built by the MODBUS slave each time the master asks to perform a non-authorized action/command. VPGate PROFIBUS MODBUS manages the following exceptions : Exception code Name Description 01 ILLEGAL FUNCTION Sent by the slave each time the master sends an unknown command. VPGate MODBUS only support the functions (commands) 1, 2, 3, 4, 5, 6, 7, 15, 16, 23. 02 ILLEGAL DATA ADDRESS Sent by the slave each time the master tries to access to a nonaccessible register. For example, VPGate has got a configuration with 10 read registers (address 0 to 9), and 10 write registers (address 0 to 9). An error is returned when the master tries to access to register 20. This error also appears with the function 3 when for example the master tries to read 20 registers from register 1 (address 0). 03 ILLEGAL DATA VALUE This exception is sent if the master tries to write a data which is non acceptable for the slave. For example, with the function 5, the 2 only possible values are either 0x0000 or 0xFF00. For any other value, the exception code 3 is returned. 06 SLAVE BUSY This exception is sent by a MODBUS slave when it is already working on a task that doesn't allow it to respond. 0A GATEWAY PATH UNAVAILABLE This exception is sent, in slave mode, in reply to any MODBUS query when PROFIBUS communication is not established.

Format of the exception message: This exception message is an example received in reply to the function 6. The exception happened because the master tried to access to a non-authorized register. The MODBUS function codes are coded on 7 bits (code 1 to 127). The 8 th bit is reserved, it is used to signal an exception message when it is set to 1.
